Install the Large Mounting Shelf in an Open-Frame Rack

Before front-mounting the router in an open-frame rack, install the large mounting shelf on the rack. The following table
specifies the holes in which you insert screws to install the mounting hardware in an open-frame rack (an X indicates a
mounting hole location). The hole distances are relative to one of the standard U divisions on the rack. For reference, the
bottom of all mounting shelves is at 0.04 in. (0.02 U) above a U division.

X0.88 in. (2.2 cm) 0.50 U2

1. On the rear of each rack-rail, install cage nuts, if needed, in the holes specified in the table.

2. Partially insert a 12-24, ½-in. screw into the highest hole specified in the table.

3. Hang the shelf over the mounting screws using the keyhole slots located near the top of the large shelf flanges.

4. Partially insert screws into the open holes in the flanges of the large shelf.

Mount the EX9214

NOTE: A fully loaded chassis weighs approximately 350 lb (158.76 kg). We strongly recommend that you use

a mechanical lift to lift the chassis, and remove all the components from the chassis before mounting.

NOTE: While mounting multiple units on a rack, mount the heaviest unit at the bottom and mount the other

units from the bottom to the top in order of decreasing weight.

To install the switch using a mechanical lift:

1. Safely remove all components—power supplies, Switch Fabric (SF) module, fan tray, air filter, and line cards—from the
chassis.

2. Ensure that the rack is properly secured to the building in its permanent location. Ensure that the installation site allows
adequate clearance for both airflow and maintenance. For details, see the Complete Hardware Guide for EX9214
Switches.

3. Ensure that the mounting shelf is installed to support the weight of the switch.
